Upscale Requirement Calculator
Calculate how much additional pixel resolution would be required to hit a target print size and PPI.
Enter your job values
Use the real values from your job. Optional fields can stay blank; zero should only be used when the value genuinely does not apply.

What the result is useful for
Upscale Requirement Calculator is useful when you need to turn pixel dimensions and a physical output size into a decision about resizing, cropping or whether the source file has enough raster detail.
How the calculation works
Required pixel scale is the larger of required-width/source-width and required-height/source-height so both axes meet the target.
What this calculator cannot know
The math can describe pixels, PPI and geometry, but it cannot judge subject detail, sharpening, resampling quality, printer process, media or viewing distance. Use the output provider’s requirement when one exists.
